Music RACK.

Appncanmifiied 'March 2, ieee. serial Nopsrroe. i

My invention relates to music racks1 more particularly to n'iusic'ra'cksV which are adapted for changing sheet music without requiring the use of `the"operatorie hands.

It is among the objects otmy invention to provide ai music rack embodying means 'lor rapidly changingsheet music to give the musician an uninterruptedview. of his notes vsheet music of an e'ntire program inthe position in which itis read, thereby Veliminatingythe confusion and interruptions caused' bythe turningand sorting ofthe sheetsdnr- .ing the renditionoi the music.

Another object of my invention is to produce a niusicrack of simple, compact and durable mechanical construction provided y .withineans for presenting the sheets ot notes to the musician in their proper order with facil-ity anddispatch. Y

It is the common experience ol musicians to interrupt their playing on Vaccount of the necessity for turning or replacing their sheet music during the playing of a musical iiiiiiiT ber or betweensuccessive numbers, resultingin confusion kand noticeable interruptions.

My present inventionl relates to a music rack `which is intended to overcome these ditliculties by providing a. continuous and uninterrupted yview of sheet music to the musician during the rendition of an entire musical program.A Y y p In accordance with my invention lprovide'a music rack comprisingy a! table or `frame supported on a suitable standard,

which table is adapted to journal for rotation a plurality of 'winding drums in spa-ced relation for mounting a-kcarrier or belt to whiclithe sheet music isattached inlthe position in which it is normally readby `the musician. The belt or carrier is secured at fits respective ends to the drums and is adapted to be simultaneously iiiireeledV from one ofthe drums and wound on the other `while traversing the table n'iember.'

suitable manner as byv means of'y a pair of cranks provided with foot pedals.

In the accompanying drawings constitutfing a Vpart hereof, and in vwhich like reference`"`characters designatelile parts, Fig; 1 is a front elevational view of amiisic rack embodying the principlesof my iiivei'itioii; `Fig. Q'is a view partially inV section and 'partially in side elevation ottlieracl shown in Fig.. l taken yalong the line lllthereot; Fig. 3 is a view in "cross sectionjof thetab'le member ot' the rack 'shown. inv an inclined position; Figa is a partialplaii view ot the table and drums illustrating theV position of the sheet music in traversing 'across the table from one drum toanotherirlig. 5

Ais a sectional view taken along the line .Y-V, Figa; 6 is' .a longitudinal sec# (tional view partially in elevation taken along the line yVI-,VLFig. 5.; 7 asectional view ot'a fragmentaryportion of the table taken along the line VII-QVILFig. 6.; Figs.

8 to 12, inclusive, are plan views of the belt or carrier member to secure the sheet iniisic whichis carried by the winding drums; Fig.

'13 is a sectional view take-n 'along the line I-I, Fig.112, and Figs. ll'to'ilS, inclusive,

ingY various means of fastening Vthe strips within which the sheets of music are located.

Referring to Figs. 2 and 3 of the drawings the structure therein illustrated Vcoinprises a table member 1p having Vextending side frame portions 2 provided withwbrackets 3 for rotatablyY journaling ay pair ot winding drums t having extending end flanges 5. The table 1 is provided with a plurality of hinge brackets 6 having openings 7 by which it is pivotally secured to a pair of hollow triinnionsB' which are tastened or integrally formed to a standard or vertically extendino supporting member 9 having an expanded base 10 to provide the necessary stability for the entire structure. rlhe central portion ot the table 1 is provided with a bi'furcated bracket 1l having an arin 12 pivotally securedth'ereto which fis provided with openings 13 adapted to receive a pin 14 by means of which the arm 12 is secured in any desired position with respect to a bracket 15 laterally project-ing with standard 9. By means ot this adjustment the table 1 may be inclined as shown in Fig. 3 toadjustV the position of the music relative to the' vision oi the musician.

the right-hand drum tothe surface of the table 1v and from the table member to the lower region of the left-hand drum thereby maintaining a proper tension to keep the sheets of music taut and also to prevent crimping and distortion thereof.

.The operation of my music rack is briefly as follows: With thebelt or carrier to which the 'sheet music is secured arranged in the manner shown in Fig. 4, that is, with the belt wound on the right-hand drum member and one end secured to the left-hand drum member extending from the underside of the drums across the table member as previously explained, the sheet music is presented to the View of the musician, and after reading the notes on both of the sheets in view he places the lever 23 in the position shown in Fig. 4,

to and for engagement of the clutch Z1 with the clutch faces 2() of the sheave wheel 16. This position is maintained during the subsequent unreeling of the belt from the righthand drum and for winding of the same on the left-hand drum. The operation of the foot pedals by the musician will cause the left-hand drum to rotate in a clockwise direction by virtue of the spline connection of the shaft 18 with the clutch member 21 and the connection of the latter with 'the beltoperated sheave Wheel 16, the right-hand drum being disengaged from its cooperating' clutch will rotate independently of the drive mechanism, the sheave wheel 17 being diseni raged from the clutch 21 will -also idle on the shaft 19 thereby permitting the drum to unreel at a speed corresponding to the pe ripheral winding speed of the left-hand drum which increases with the increase in diameter of the belt or music carrier as it is being wound thereon.

Vhen all of the music has been passed across the supporting table inthe manner described the lever 23 is shifted to disengage the clutch with the sheave wheel 16 and engage the clutch with the sheave wheel 17, by subsequent actuation of the drive mechanism, thereby unreeling the yleft-hand drum and winding the carrier belt on the righthand drum, which again places the sheet music in position for use for a subsequent performance.

It is evident from the foregoing description of my invention that a music rack made in accordance therewith provides a simple and efhcient means for presenting the sheet music before a musician without interruption or confusion and without subjecting 'the musician to any discomfort or inconvenience. It is further evident that a rack conf structed in the manner herein described is relatively inexpensive and can be manufactured at a costand in such quantities asl to make it available for use by musicians gen-` erally, and that from the nature of my device that it may be utilized for numerous exhibiting purposes where it is desired to expose .consecutive objects such as reading matter, pictures or thelike.

Although I have described a specic embodiment of my invention it ywill be obvious to those skilled in the art that various modifications may be made in the design and arrangement of the several structural features as for instance in the positioning of the winding drums to havethe music pass in a vertical rather than a longitudinal direction as shown, without departing from the principles herein set forth.
